Nonprofit Allies are national nonprofit organizations that support the public lands community but are not associated with a specific park, refuge, or area.  

The Corps Foundation engages the public to ensure the environmental health and recreational enjoyment of our nation’s lakes and waterways administered by the US Army Corps of Engineers.

With nearly 1.4 million members and supporters, the National Parks Conservation Association (NPCA) acts as a voice for America’s national parks, working to protect and preserve our nation’s most iconic and inspirational places for present and future generations. NPCA celebrates the parks — and works tirelessly to defend them — whether on the ground, in the courtroom or on Capitol Hill.

As the official nonprofit partner of the National Park Service, the National Park Foundation generates private support and builds strategic partnerships to protect and enhance America’s national parks for present and future generations.

“With so many SCA alumni actively engaged in protecting our public lands, there’s a natural synergy between our organizations. The PLA network is considerable, and this partnership has proven to be an effective component of SCA’s alumni relations strategy."
